By default the ultraWinGrid pops up a delete confirmation box for any row deletions. How do I turn that feature off?
If I'm deleting in the code, it's no problem:
myUltraGrid.DeleteSelectedRows(False)
But I don't know how to apply that when the user presses the delete key.
You can detect when they press the delete key on your row. Use something like the BeforeRowsDeleted event. That event exposes the BeforeRowsDeletedEventArgs object which has the e.DisplayPromptMsg property available to you.
private void ultraGrid_BeforeRowsDeleted(object sender, BeforeRowsDeletedEventArgs e)
{
e.DisplayPromptMsg = false;
}
